13.1.2 FOE features
The following table lists the features available with the Fiber Optic Extender.
Feature Description
Supported
family
Series C and PM I/O
Topology
types
Point-to-point Two systems (nodes) connected by a single cable set.
Daisy chain Multiple systems connected in a serial manner. Each module acts
like 'a repeater' allowing greater fiber distances.
Star
Sometimes
compared to a
'chicken foot'
Topology whereby all nodes are individually connected to a central
connection point. More cable is needed, but if one cable fails, the
rest of the nodes remain operational.
